Abstract
GBMs (glioblastomas), or grade IV astrocytomas/gliomas, are the most frequent and aggressive brain tumours, whose diagnosis and treatment is still inefficient. RTKs (receptor tyrosine-kinases), mainly EGFR, and their downstream pathways are altered in almost 90% GBMs. RTKs, are relevant for the regulation of GBM tumourigenesis and dissemination and for GSCs (GBM stem cells), a GBM subpopulation that display stem-like and GBM-initiating properties. Dissemination is also linked to GBM aggressiveness. EMT (epithelial-mesenchymal transition)-like processes would facilitate the acquisition of a more mesenchymal and invasive phenotype. Both, stemness and disseminative capacity have been associated to GBM recurrence and therapy resistance...
